The band played a surprise set during the traveling festival's stop in Ventura, California on Sunday. They treated fans to a seven-song setlist that ranged from early classics like "One Step Closer" to their latest single "Guilty All the Same" from their just-released album The Hunting Party.

To make it even more special, they invited a different Warped Tour performer to help them with each song. Some of the special guests included members of the Devil Wears Prada, Yellowcard, A Day to Remember, Finch, and more.
